A closer look with at the alcoves and lineated valley fill seen in Fig 1. The locations of these THEMIS & higher resolution MOC images are marked in Fig. 1a.
- Four alcoves cutting into the plateau at the bottom of the picture, each with a lobes flowing down and outwards into the adjacent lineated valley fill. Note how these lobes merge trends of the lineated valley fill on the valley floor tothte left.
- East-facing alcoves with multiple concentric-ridged lobes extending east and converging with the lineated valley fill on the valley floor
- An even closer look at the deformed ridges and pitting on the valley floor of Fig. 2b.
- The outflow of two ridged lobes from alcoves (bottom left and right) as they join a major lineated vally fill of area C (upper right) near the convergence with B (Fig. 1c). The left lobe is swept westward, forming broad arcing folds while the right lobe is increasingly compressed until it resembles a tight isoclinal fold. Both lobes ultimately merge into the general lineated valley fill parallel to the valley walls.
- Detail of siedways lobe-like flows converging into the lineated valley fill on the valley floor, where flows merge from areas A and D.
- A major east-facing zone of multiple alcoves and converging lobe-like flows in the more disatant reaches of the system, along the edge of the northernmost large mesa (area G). Note the concentric-outward ridges reaching out from the alcoves and their progressing compression, folding and flattening as the ridges deform and become part of the lineated valley fill on the valley floor.
- The northern reaches of the lineated valley system. The lineated valley fill splits in two (bottom right) and flows around a massif to create a broad up-flow collar and a diffuse, down-flow wake.
